The invention relates to improvements in leather belt dressings. Anobject of the invention is the provision of a composition which willsoften the belt and make it pliable and at the same time prevent it fromgetting gummy on the surface. Another object is therovision of acomposition in which own belt-dressing ingredients, preffully describedhereinafter in the following specification, and particularly pointed outin the appended claims.

The above objects are best effected by the use of an 'oily halogensubstitution productof naphthalene, in addition to. other ingre dientssuch as castor oil and preferably in addition to both castor oil andneats foot oil. The halogen substitution product preferably takes theform of mono-chloro naphthalene or of an oily product which ascommercially made. conslsts chiefly of monochloro. naphthalene with theaddition of minor proportions of higher chlorine'substitution productsof naphthalene. Neats foot oil and castoroil are well known as effectivenatural lubricants and softeners for leather. Belt dressings areknown inwhich neats foot and castor oils are incorporated with various solventswhich aid in carrying the same into the belt. These solvents, however,are sometimes of such nature as to be injurious to the leather andsometimes are volatile. When such solvents are used the. neats foot andcastor oils will not be carried into the body of the leather as far aswhen the oily halogen substitution product of naphthalene referredto'herein is used, and in such cases the surface of the belt is verylikely to be left, inja gummy condition because of the presence thereonof sticky ingredients such as the castor oil when the solvent hasevaporated.

The mono-chloro naphthalene orlequiva, lent material, which incorporatein the belt dressin is a solvent for both castor oil and neats oot oil.This oily substance is non-volatile, has low viscosity and a. greaterApplication fl led April 28, 1925.. Serial. No. 25,439.

chlorinated naphthalene. Neats foot and' castor oils are soluble in thismaterial in various proportions. It is believed that proportions ofapproximately '33 of each of the three ingredients preferably present,namely neats foot and castor oil and mono-chloro naphthalene, arepreferable.

When this composition is used, lubrication is apparently supplied toeach of the tiny fibres within the body of the leather belt and notmerely to the fibres lying close to the surface. This is because of theunusual penetrating qualities of the oily chlorinated naphthalene. Itmakes the belt soft and pllable and atthe same time prevents gumming onthe surface of the belt because of the fact that all of the lubricant isapparently carried into the body of the leather. The use of thecomposition insures sary to insure a good grip on the pulleys,

while at the same time the composition introduces into the belt noharmful adhesives which may serve temporarily to make possible thecarryingof a load for which the drive was not designed but which areharmfill in the long run. It may =1ikewis'e be noted that thecomposition will notbecome rancid and that its use prevents mildewon thebelt because of the fact that the chlorinated naphthalene is a germicideand fungicide. 1

While the composition preferably consists of the use of the threeingredients noted, it is not necessarily limited to the'use of thesethree specific elements, reasonable equivalents of the same beingincluded Within the scope ofthe invention. It should be also noted that,while best results are obtained by the use of both neats foot and withinthe scope of the invention. In this from thecomposition than the castoroil.

lWhat'I claim is: I

1. A belt dressing comprising neats foot oil, castor oil, and an oilyhalogen substitution product of naphthalene.

2. A belt dressing comprising neats foot oil and castor oil dissolved inan oily' halogen substitution product of naphthalene.

3. A belt dressing coniprisingneats foot oil and castor oil dissolved inan oily chlo-' rinated naphthalene having a low viscosity. 4. A beltdressing comprising neats foot oil and castor oil dissolved in an oilyprodnot of low viscosity consisting chiefly of mono-chloro-naphtha ene.

5. A belt dressing comprising about equal proportions of neat s footoil, castor oil, and an oily halogen substitution product of nahthalene.

'. A belt dressing comprising castor oil and an oily non-volatilehalogen substitution product of naphthalene having low viscosity.

7. A belt dressing comprisingcastor oil and an oily product of lowviscosity consisting chiefly of mono-chloro-naphthalene.

8. A belt dressing comprising oily leather lubricating and softeningelements dissolved in an oily halogen substitution product of'naphthalene.

In testimony whereof I have signed my name to this specification.
